Description

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to U.S. Application No. 63/221,097, filed on Jul. 13, 2021, the contents of which is hereby incorporated by reference in it's entirety.

TECHNICAL FIELD

The invention relates to musical instruments, and in particular, to cases for musical instruments.

BACKGROUND

When transporting a guitar, it is useful to place the guitar in a case. Such a case protects the guitar from impact and provides a place to store paraphernalia that is used when playing a guitar, such as picks, tuners, tuning bars, and spare strings.
Known guitar cases have devices that assist in carrying the case. Such devices include a handle as well as straps to enable the guitar to be carried on one's back.
In some cases, guitars are deceptively heavy. For example, although the body of a solid body guitar is small, it is quite dense and heavier than it appears. For this reason, it is preferable to be able to roll the case instead of carrying it.
Aside from the weight of the guitar itself, another difficulty that arises with carrying a guitar on one's back is that the guitar's neck is long. This is particularly true for a bass guitar. As a result, the top end of the case can be higher than a person's head. It is thus easy to accidentally hit such objects as door's head jamb, a low-hanging chandelier, or, in particularly unfortunate cases, a rapidly spinning electric fan.
To avoid this difficulty, certain guitar cases have been made with wheels, much like wheeled luggage. However, known wheels are inconvenient to use and somewhat fragile.

DETAILED DESCRIPTION

FIG. 1 shows a chordophone case 10 that is particularly configured for accommodating a guitar or other chordophone having a structure similar to the guitar. Examples of such chordophones include a bass, a cello, and a contrabass.
The illustrated case 10 includes a handle 12, a front face 14, and a footing 16 separated from the body by a seam 18. The guitar case 10 further includes a pair of front anchors 20 that are offset on either side of a midline that bisects the guitar case 10.
FIG. 2 shows a rear face 22 of the same chordophone case 10. A shoulder harness 24 and a pair of rear anchors 26 attach to the rear face 22. Like the front anchors 20, the rear anchors 26 are offset on either side of the midline that bisects the chordophone case 10. The offset used for the rear anchors 26 is the same as that used for the front anchors 20.
Each of the front and rear anchors 20, 26 has an anchored end 28 and an attachment end 30. An anchor's anchored end 28 attaches to the chordophone case 10 and an anchor's attachment end 30 is used for attaching the front or rear anchor 20, 26 to a wheel assembly 32, which is best seen in FIG. 3 .
In the illustrated embodiment, the front anchor 20 comprises a front-anchor strap 34 having a front-anchor-strap proximal end 36 and a front-anchor-strap distal end 38. The front-anchor-strap proximal end 36 has been sewn into the seam 18 at the front anchor's anchored end 28. The front-anchor-strap distal end 38 passes through a front loop 40 and is then sewn onto a distal portion of the front-anchor strap 34, thus forming a loop. This loop secures the front loop 40 to the front-anchor strap 34 and forms the front anchor's attachment end 30.
In the illustrated embodiment, the rear anchor 26 comprises a rear-anchor strap 42 having a rear-anchor-strap proximal end 44 and a rear-anchor-strap distal end 46. The rear-anchor-strap proximal end 44 has been sewn onto the rear face 22 at the rear anchor's anchored end 28. The rear-anchor-strap distal end 46 passes through a rear loop 48 and is then sewn onto a distal portion of the rear-anchor strap 42, thus forming a loop. This loop secures the rear loop 48 to the rear-anchor strap 42 and forms the rear anchor's attachment end 30.
As shown in FIG. 3 , the wheel assembly 32 comprises a fork mount 50, a frontward strap 52, and a rearward strap 54. The frontward strap 52 and rearward strap 54 extend from the strap fitting 50 in opposite directions along a rolling axis RA that bisects the fork mount 50. An axle 56 extends across a distal end of the fork mount 50 and supports a wheel 58 that is oriented to roll along a rolling direction defined by the rolling axis RA. A transverse axis TA bisects the fork mount 50 in a direction parallel to that along which the axle 56 extends.
Referring now to FIG. 4 , the fork mount 50 features a rectangular base 60 having a front edge 62, a rear edge 64 that is parallel to the front edge 62, a left edge 66 that is perpendicular to the front edge 62, and a right edge 68 that is perpendicular to the front edge 62. A front slot 70 extends along the front edge 62 and a rear slot 72 extends along the rear edge 64.
As shown in FIG. 3 as well as FIG. 5 , the rearward strap 54 has an anchored end 74 and a free end 76. The rearward strap's anchored end 74 is passed through the rear slot 72 and stitched to itself to form a permanent loop. This permanent loop anchors the rearward strap 54 to the fork mount 50. The rearward strap's free end 76 has a touch fastener 78 on an attachment face 80 thereof. The rearward strap's free end 76 is passed through the rear loop 48 and fastened to itself to form a detachable loop. This forms a detachable connection with the rear face 22 of the chordophone case 10.
While a variety of dimensions can be used, in some embodiments, the values of L1, L2, L3, and W shown in FIG. 5 are 3.125 inches, 5 inches, 10.75 inches, and 1.5 inches, respectively.
As used herein, a “touch fastener” includes such fasteners as hook-and-loop fasteners and hook-and-pile fasteners. Such touch fasteners are configured to temporarily fasten two surfaces by application of pressure and to cause surfaces thus fastened to become unfastened by application of a force in a direction opposite to that of the force that was used to apply the pressure.
The frontward strap 52 has an anchored end 82 and a free end 84. The frontward strap's anchored end 82 is passed through the front slot 70 and stitched to itself to form a permanent loop. This permanent loop anchors the frontward strap 52 to the fork mount 50. The frontward strap's free end 84 has a touch fastener 86 on an attachment face 88 thereof. The frontward strap's free end 84 is passed through the front loop 40 and fastened to itself to form a detachable loop. This forms a detachable connection with the front face 14 chordophone case 10.
The fork mount 50 comprises a first sidewall 90 and a second sidewall 92. The first sidewall 90 and the second sidewall 92 extend away from the base 60 along a direction that forms an oblique angle relative to a plane defined by the base 60 and in the direction along which the rearward strap 54 extends. As shown in FIG. 6 , the oblique angle is selected such that the footing 16 and the wheel assemblies 32 cooperate to support the chordophone case 10 as shown in FIG. 6 .
In some embodiments, the wheel 58 comprises polyurethane or nylon with a hub that comprises a thermoplastic polymer such as polycarbonate or acrylonitrile butadiene styrene and the various straps 34, 42, 52, 54 comprise polyester webbing. Because of its greater ruggedness, the use of polyurethane is particularly advantageous for use outdoors on potentially irregular and rougher rolling surfaces.
The chordophone case 10 is thus transformable between a wheeled state and an unwheeled state. To transform the chordophone case 10 into the wheeled state, one simply attaches the frontward and rearward straps 52, 54 to the corresponding front and rear anchors 20, 26 on the chordophone case 10. To transform the chordophone case 10 into the unwheeled state, one detaches the frontward and rearward straps 52, 54 and stows them in a convenient location they will be readily available. With the wheel assembly 32 having been thus removed, it is possible to use the shoulder harness 24 without the discomfort that may arise from the presence of the wheel assembly 32. The resulting multi-modal chordophone case 10 can thus be transported using the shoulder harness 24, the handle 12, or the wheel assemblies 32.
In the illustrated embodiment, the touch fasteners 78, 86 are part of the wheel assembly 32 and the front and rear loops 40, 48 are part of the front and rear anchors 20, 26, respectively. However, in alternative embodiments, the touch fasteners are on the front and rear anchors 20, 26 and the front and rear loops 40, 48 are part of the wheel assembly 32. In a broad sense, the wheel assembly 32 is one that can be attached to and detached from the front and rear anchors 20, 26 with a level of ease that is comparable to that associated with attaching and detaching a strap from a briefcase.
The illustrated embodiment is a chordophone case that is specific to accommodating a guitar and similar lute-like instruments, including a banjo, a bass guitar, a cello, and a contrabass.
It is to be understood that the foregoing description is intended to illustrate and not to limit the scope of the invention, which is defined by the scope of the appended claims. Other embodiments are within the scope of the following claims.
